RESUMO
Background: Adhesive small bowel obstruction (ASBO) is a common acute abdominal complication. Although non-surgical treatment is the primary treatment approach, more and more studies show that surgical treatment can reduce the incidence rate. Laparoscopic adhesiolysis (LA) has many advantages of minimally invasive surgery.But not all patients with ASBO are suitable for LA. Objective: The aim of this scoping review was to summarize the keys to successful LA by analyzing the extensive literature. Methods: A literature search was conducted in PubMed for articles on laparoscopic treatment of ASBO published between January 2000 and February 2024. This scoping review followed the framework suggested by Arksey and O'Malley for a scoping review. Results: By analyzing the included studies we found that LA does have many advantages and can be performed safely. However, the prerequisite is to select patients with simple adhesions whenever possible and to focus on reasonable intraoperative measures. To improve the success rate of LA, we summarized the following characteristics of patients: no contraindications related to pneumoperitoneum, few previous abdominal operations (≤2), no pregnancy, bowel dilatation < 4 cm in diameter, simple adhesions, no diffuse peritonitis, no history of abdominal radiotherapy, <24 h of ASBO, limited previous abdominal surgery (appendix, cholecystectomy), no bowel strangulation ischemia, and bowel necrosis or bowel resection required for other reasons. In addition, we also summarized reasonable intraoperative measures. Conclusions: Laparoscopic adhesiolysis has many advantages.Specific patients can benefit from LA. This scoping review Summarized the conditions for patient screening and reasonable intraoperative measures with the aim of providing a reference for surgeons, thereby ensuring that more patients benefit from LA.
RESUMO
Adhesive small bowel obstruction is thought to be a disorder limited to the jejunum and ileum. As a result, the list of aetiologies for duodenal obstruction does not include adhesions. We report the case of a patient who presented with gastric outlet obstruction (GOO), but with no lesions identified on cross-sectional imaging or endoscopy. Laparoscopy revealed duodenal adhesions as the cause of her GOO. Kockerization of the duodenum led to resolution of her symptoms. This previously undocumented finding leads us to suggest that laparoscopy should be considered in patients who have features highly suspicious for GOO, but have no cause identified on investigation.
RESUMO
PURPOSE: This study aimed to identify the radiological CT findings that are significantly correlated with the outcome of conservative management with oral water-soluble contrast medium in patients presenting with Adhesive Small Bowel Obstruction (ASBO) to the Emergency Room. METHODS: In this retrospective single-center study, we considered all consecutive patients admitted to the ER from February 2019 to February 2023 for ASBO with an available contrast-enhanced CT scan performed at diagnosis and treated with conservative management. The investigated CT findings were type and location of transition zone, ASBO degree, fat notch sign, beak sign, small bowel feces sign, presence of peritoneal free fluid and pneumatosis intestinalis. Radiological parameters were analyzed using univariable and multivariable logistic regression to test the significant association between the CT parameters and the target. RESULTS: Among the 106 included patients (median age 74.5 years), conservative treatment was effective in 59 (55.7%) and failed in 47 (44.3%), needing delayed surgery. In the failure group, there was a higher prevalence of patients who had previous ASBO episodes (p = 0.03), a greater proportion of females (p = 0.04) and a longer hospital stay (p < 0.001). At multivariable analysis, two CT findings were significantly correlated with failure of conservative treatment: fat notch sign (OR = 2.95; p = 0.04) and beak sign (OR = 3.42; p = 0.04). CONCLUSIONS: Two radiological signs correlate with failure of non-operative management in ASBO, suggesting their importance in surgical decision-making. Patients presenting with these signs are at higher risk of unsuccessful conservative treatment and may require undelayed surgical intervention.
RESUMO
BACKGROUND: Acute small bowel obstruction (SBO) is a common surgical emergency. The study aims to provide a comprehensive clinical-epidemiological description of SBO in adults at a tertiary care center in western India. METHODS: This hospital-based cross-sectional study was conducted from July 2020 to June 2022 and enrolled 88 SBO patients requiring surgical intervention. After adequately resuscitating the patients, various surgical procedures were performed based on the intraoperative conditions of the bowel. Patients were assessed postoperatively for the duration of their hospital stay, postoperative complications, and surgical recovery. RESULTS: There was a male preponderance (n=55), with a median age of 50 (18-90) years. Abdominal discomfort was the most frequent symptom, necessitating a hospital visit (97.9%, n= 86), followed by nausea (85.2%, n= 75), constipation (78.1%, n=69), and abdominal distension (51.1%, n=45). Ileal strictures (18.2%, n=16) were the most common etiology, followed by postoperative adhesions (14.8%, n=13) and bands (13.6%, n=12), of which 76.4% (n=9) had past surgical history. Resection and anastomosis were the most frequently performed surgical interventions in this study (36.4%, n=32), followed by stoma creation (27.3%, n=24) and adhesiolysis (17%, n=15). The postoperative 30-day mortality of 11.36% (n=10) was noted, which could be ascribed to the elderly population with comorbidity, postoperative complications, and who required extended stay in the critical care unit. CONCLUSION: Benign ileal stricture was the most common cause of acute SBO in the emergency. Prompt and timely diagnosis combined with a multidisciplinary approach and effective management can improve outcomes and reduce morbidity and mortality in adult patients with SBO.
RESUMO
Optimal treatment for adhesive small bowel obstruction (SBO) is not defined. Surgery is the only method of treatment for obvious strangulating SBO. Non-operative management (NOM) is widely used among patients with low risk of strangulation, i.e. no clinical, laboratory and CT signs. Randomized controlled trials (RCTs) are recommended to determine the optimal method (early intervention or NOM), but their safety is unclear due to possible delay in surgery for patients needing early intervention. MATERIAL AND METHODS: A RCT is devoted to outcomes of early operative treatment and NOM for adhesive SBO. The estimated trial capacity is 200 patients. Thirty-two patients were included in interim analysis. In 12 hours after admission, patients without apparent signs of strangulation were randomized into two clinical groups after conservative treatment. Group I included 12 patients who underwent immediate surgery, group II - 20 patients after 48-hour NOM. The primary endpoint was success of non-surgical regression of SBO and reduction in mortality. To evaluate patient safety, we analyzed mortality, complication rates and bowel resection in this RCT with previously published studies. RESULTS: In group I, all 12 (100%) patients underwent surgery. Only 4 (20%) patients required surgery in group II. Mortality, complication rates and bowel resection rates were similar in both groups. Strangulating SBO was found in 8 (25%) patients. Overall mortality was 6.3%, bowel resection rate - 6.3%, iatrogenic perforation occurred in 3 (18.8%) patients. These values did not exceed previous findings. CONCLUSION: Non-operative management within 48 hours prevented surgery in 80% of patients with SBO. Interim analysis found no significant between-group differences in mortality, complication rates and bowel resection rate. Patients had not been exposed to greater danger than other patients with adhesive SBO. The study is ongoing.

PURPOSE: The recovery of gastrointestinal function and postoperative ileus are the leading goals for clinicians following surgery for adhesive small bowel obstruction. While enhanced recovery programs may improve recovery, their feasibility in emergency surgery has not yet been proven. We sought to assess the incidence of postoperative ileus in patients following surgery for ASBO and the feasibility of enhanced recovery programs, including their benefits in the recovery of gastrointestinal functions and reducing the length of hospitalization. METHODS: This prospective study includes the first 50 patients surgically treated for ASBO between June 2021 and November 2022. Their surgery was performed either as an emergency procedure or after a short course of medical treatment. The main aim was to compare the observed rate of postoperative ileus with a theoretical rate, set at 40%. The study protocol was registered in clinicaltrials.gov under the number NCT04929275. RESULTS: Among the 50 patients included in this study, it reported postoperative ileus in 16%, which is significantly lower than the hypothetical rate of 40% (p = 0.0004). The median compliance with enhanced recovery programs was 75% (95%CI: 70.1-79.9). The lowest item observed was the TAP block (26%) and the highest observed items were preoperative counselling and compliance with analgesic protocols (100%). The overall morbidity was 26.5%, but severe morbidity (Dindo-Clavien > 3) was observed in only 3 patients (6%). Severe morbidity was not related with the ERP. CONCLUSION: Enhanced recovery programs are feasible and safe in adhesive small bowel obstruction surgery patients and could improve the recovery of gastrointestinal functions. CLINICAL TRIAL REGISTRY: NCT04929275. WHAT DOES THE STUDY CONTRIBUTE TO THE FIELD?: Perioperative management of adhesive small bowel obstruction (ASBO) surgery needs to be improved in order to reduce morbidity. Enhanced recovery programs (ERP) are both feasible and safe following urgent surgery for ASBO. ERPs may improve the recovery of gastrointestinal (GI) functions.

OBJECTIVE: Estimating which patients might require surgical intervention is crucial. Patients with complete bowel obstructions exhibit disrupted enterohepatic cycles of bile and bacteremia due to bacterial translocation. The goal of this study was to develop a prediction index using laboratory inflammatory data to identify patients who may need surgery. MATERIALS AND METHODS: The patients were divided into two groups based on their management strategy: Non-operative management (Group 1) and surgical management (Group 2). RESULTS: The indirect bilirubin, direct bilirubin, and total bilirubin were significantly higher in Group 2 than in Group 1 (p = 0.001, p < 0.001, and p < 0.001, respectively). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-NLR (PNLR), and direct bilirubin-to-lymphocyte ratio (DBR) were significantly higher in Group 2 compared to Group 1 (p = 0.041, p = 0.020, and p < 0.001, respectively). In group 2, 78% have viable bowels. Resection was performed in 40% of cases, with 12% mortality and a 10-day average hospital stay. DLR performs the best overall accuracy (72%), demonstrating a well-balanced sensitivity (62%) and specificity (81%). CONCLUSIONS: This study suggested that DBR is a more accurate predictive index for surgical intervention in pediatric adhesive small bowel obstruction patients compared to NLR and PNLR, providing valuable guidance for treatment strategies.
OBJETIVO: Desarrollar un índice de predicción utilizando datos inflamatorios de laboratorio para identificar qué pacientes podrían necesitar cirugía. MÉTODO: Los pacientes se dividieron en dos grupos según su estrategia de manejo: no quirúrgico (grupo 1) o quirúrgico (grupo 2). RESULTADOS: Las bilirrubinas indirecta, directa y total fueron significativamente más altas en el grupo 2 que en el grupo 1 (p = 0.001, p < 0.001 y p < 0.001, respectivamente). Las relaciones neutrófilos-linfocitos, plaquetas-neutrófilos-linfocitos y bilirrubina directa-linfocitos fueron significativamente más altas en el grupo 2 que en el grupo 1 (p = 0.041, p = 0.020 y p < 0.001, respectivamente). En el grupo 2, el 78% tenían intestino viable. Se realizó resección en el 40% de los casos, con un 12% de mortalidad y una estancia hospitalaria promedio de 10 días. La relación bilirrubina directa-linfocitos tuvo la mejor precisión general (72%), demostrando una sensibilidad bien equilibrada (62%) y una buena especificidad (81%). CONCLUSIONES: Este estudio sugiere que la relación bilirrubina directa-linfocitos es un índice predictivo más preciso para la intervención quirúrgica en pacientes pediátricos con obstrucción adhesiva de intestino delgado en comparación con la de neutrófilos-linfocitos y la de plaquetas-neutrófilos-linfocitos, proporcionando una valiosa orientación para las estrategias de tratamiento.

BACKGROUND: Empty Pelvis Syndrome, subsequent to the removal of pelvic organs, results in the descent of the small bowel into an inflamed pelvic cavity, leading to the formation of adhesions and subsequent small bowel obstruction. However, no effective measures have been previously described. OBJECTIVE: Describe a simple and autologous solution to prevent "Empty Pelvis Syndrome," small bowel obstruction, and adhesions by utilizing the cecum to occlude the pelvis. DESIGN: Mobilization of the right colon to lower the cecum into the pelvic cavity to occlude the superior pelvic ring to some degree and changing the direction of the terminal ileum. SETTINGS: Hospital Universitario Fundación Jiménez Díaz, Department of General Surgery, Colorectal Service. PATIENTS: Eight anonymized patients were included in this study, each with varying colorectal pathologies. Patients were above 18 years old. MAIN OUTCOME MEASURES: Percent of blockage of the superior pelvic ring produced by the descended cecum recorded in percentage; the amount of small intestine descended past the superior pelvic ring recorded in cm. RESULTS: The mobilization of the cecum achieved partial occlusion of the superior pelvic ring. The descent of the small bowel beyond this landmark ranged from 0 to 4.9 cm. LIMITATIONS: Given the small number of patients included in this study, these results cannot be generalized to the whole of the population. A bladder emptying protocol prior to CT scans was not implemented, resulting in variations in measurements among patients. CONCLUSION: The cecum-to-pelvis technique is a simple method that can serve as an autologous solution to EPS (enteropelvic fistula) and help reduce postoperative complications such as SBO (small bowel obstruction) and adhesions. It is not essential to completely occlude the superior pelvic ring to achieve successful outcomes.

Background: Postoperative complications in adhesive small bowel obstruction (ASBO) significantly escalate healthcare costs and prolong hospital stays. This study endeavors to construct a nomogram that synergizes computed tomography (CT) body composition data with inflammatory-nutritional markers to forecast postoperative complications in ASBO. Methods: The study's internal cohort consisted of 190 ASBO patients recruited from October 2017 to November 2021, subsequently partitioned into training (n = 133) and internal validation (n = 57) groups at a 7:3 ratio. An additional external cohort comprised 52 patients. Body composition assessments were conducted at the third lumbar vertebral level utilizing CT images. Baseline characteristics alongside systemic inflammatory responses were meticulously documented. Through univariable and multivariable regression analyses, risk factors pertinent to postoperative complications were identified, culminating in the creation of a predictive nomogram. The nomogram's precision was appraised using the concordance index (C-index) and the area under the receiver operating characteristic (ROC) curve. Results: Postoperative complications were observed in 65 (48.87%), 26 (45.61%), and 22 (42.31%) patients across the three cohorts, respectively. Multivariate analysis revealed that nutrition risk score (NRS), intestinal strangulation, skeletal muscle index (SMI), subcutaneous fat index (SFI), neutrophil-lymphocyte ratio (NLR), and lymphocyte-monocyte ratio (LMR) were independently predictive of postoperative complications. These preoperative indicators were integral to the nomogram's formulation. The model, amalgamating body composition and inflammatory-nutritional indices, demonstrated superior performance: the internal training set exhibited a 0.878 AUC (95% CI, 0.802-0.954), 0.755 accuracy, and 0.625 sensitivity; the internal validation set displayed a 0.831 AUC (95% CI, 0.675-0.986), 0.818 accuracy, and 0.812 sensitivity. In the external cohort, the model yielded an AUC of 0.886 (95% CI, 0.799-0.974), 0.808 accuracy, and 0.909 sensitivity. Calibration curves affirmed a strong concordance between predicted outcomes and actual events. Decision curve analysis substantiated that the model could confer benefits on patients with ASBO. Conclusion: A rigorously developed and validated nomogram that incorporates body composition and inflammatory-nutritional indices proves to be a valuable tool for anticipating postoperative complications in ASBO patients, thus facilitating enhanced clinical decision-making.
RESUMO
Adhesive small bowel obstruction (ASBO) causes a major burden in emergency medicine. Owing to in situ decompression, nasointestinal tube (NIT) placement has been increasingly used in clinical practice compared with traditional conservation (TC); however, the indications remain controversial. This study was designed to explore the indications for each treatment in ASBOs and then suggest the optimal strategy. After propensity score matching, 128 pairs were included (the NIT and TC groups). The occurrence of severe adverse events (SAEs), peri-treatment clinical parameters, and radiological features were compared between the successful and failed treatment groups. According to different stages of the entire treatment, the independent risk factors for adverse effects for ASBO were analysed in phase I and phase II. In phase I, normal red blood cells (RBC) levels (p = 0.011) and a balanced sodium ion level (p = 0.016) positively affected the outcomes of TC treatment. In phase II, for the TC group, the successful treatment rate reached 79.5% for patients with ASBOs whose normal RBC levels (p = 0.006) or decreasing white blood cells (WBC) levels (p = 0.014) after treatment. For the NIT group, the treatment success rate was 68.1% for patients whose electrolyte imbalance could be reversed or whose neutrophil count/lymphocyte ratio (NLR) levels was lower than 4.3 (p = 0.018). TC treatment is highly recommended for patients with normal RBC counts and sodium levels pretreatment. After dynamic monitoring of the treatment process, for both the TC and NIT groups, once ASBOs had elevated inflammatory biomarkers or irreversible electrolyte disturbances, surgical interference was preferred.

BACKGROUND: There are limited data identifying predictors of postoperative outcomes in adhesive small bowel obstruction (ASBO). This study used the National Inpatient Sample (NIS) to assess the efficacy of the modified frailty index (mFI) to predict postoperative morbidity among patients undergoing an operation for ASBO. METHODS: A retrospective analysis of the NIS between September 1, 2015, and December 31, 2019, was performed to identify adult patients who underwent nonelective operative intervention for ASBO. The mFI was used to stratify patients as either frail (mFI value ≥ 0.27) or robust (mFI value < 0.27). The primary outcomes were overall in-hospital postoperative morbidity and mortality. The secondary outcomes were system-specific morbidity, length of stay (LOS), total in-hospital healthcare cost, and discharge disposition. Univariable and multivariable regressions were used. RESULTS: Overall, 23251 robust patients and 6122 frail patients were included. Adjusted analyses demonstrated that frail patients had increased in-hospital mortality (adjusted odds ratio [aOR], 2.16; 95% CI, 1.80-2.60), postoperative morbidity (aOR, 1.63; 95% CI, 1.52-1.74), postoperative LOS (adjusted mean difference [aMD], 0.97 days; 95% CI, 0.73-1.21), and total in-hospital healthcare costs (aMD, $18,921; 95% CI, $14,608-$23,235) and were less likely to be discharged home (aOR, 0.59; 95% CI, 0.55-0.63). The findings were unchanged on subgroup analysis of patients undergoing open operation and those older than 65 years of age. CONCLUSION: The mFI may predict postoperative outcomes for ASBO. Stratifying patients based on frailty may assist clinicians and patients in making informed decisions, setting realistic expectations, and proactively planning postoperative disposition.

INTRODUCTION: Studies identifying predictors of postoperative outcomes in adhesive small bowel obstruction are limited. This study investigates the efficacy of the modified frailty index (mFI)to predict postoperative morbidity and mortality among patients undergoing surgery for adhesive small bowel obstruction. METHODS: A multicentre retrospective cohort study including patients undergoing surgery for adhesive small bowel obstruction after failed trial of nonoperative management between January 2015 and December 2020 was performed. Impact of frailty status using the mFI, stratified as frail (≥0.27) and robust (<0.27), on postoperative morbidity, mortality, length of stay, and discharge destination was evaluated using multiple logistic regression. RESULTS: Ninety-two robust patients (mean age 62.4 y, 68% female) and 41 frail patients (mean age 81.7 y, 63% female) were included. On simple stratification, frail patients had significantly increased 30-d morbidity (overall morbidity 80% versus 49%) and need for higher level of care on discharge (41% versus 9%). However, on multiple regression, functional dependence but not the mFI, was independently associated with worse 30-d overall morbidity (odds ratio [OR] 3.97, confidence interval [CI] 1.29-12.19) and lower likelihood of returning to preoperative disposition (OR 0.21, CI 0.05-0.91). The delay in operation beyond 5 d was independently associated with worse 30-d outcomes including overall morbidity and mortality (OR 7.54, CI 2.13-26.73) and decreased return to preoperative disposition (OR 0.14, CI 0.04-0.56). CONCLUSIONS: The mFI, although promising, was not independently predictive of outcomes following surgery for adhesive small bowel obstruction. Further adequately powered studies are required.

Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disorder, characterized by recurrent and self-limiting episodes of fever and serosal inflammation. Recurrent serositis may rarely lead to the formation of adhesions in the peritoneum, which may result in mechanical bowel obstruction. The symptoms, such as abdominal pain and vomiting, may mimic typical FMF attacks, resulting in misdiagnosis and severe morbidity, including strangulation and intestinal necrosis. Physicians are generally aware of other complications associated with FMF but reports on peritoneal adhesions and intestinal obstruction in English-language literature are inadequate to increase clinicians' awareness. Therefore, it is crucial to meticulously evaluate FMF patients presenting with abdominal pain and ileus because these symptoms could be due to adhesive small-bowel obstruction (ASBO). Furthermore, patients presenting with ASBO without a history of abdominal surgery should also be thoroughly evaluated, especially as it could be an initial presentation for an autoinflammatory disease. Herein, we present a pediatric case of FMF with the M694V homozygous mutation, complicated by ASBO while under colchicine treatment. Additionally, we provide a comprehensive review of the available literature on ASBO in FMF.

The adoption of laparoscopy for the management of adhesive small bowel obstruction (ASBO) patients is debated. The laparoscopic approach has been associated with a considerable conversion-to-open rate. Nonetheless, reliable predictors of conversion are still unclear. The present study aimed to identify factors associated with conversion to open in ASBO patients who underwent laparoscopic surgery. Patients who underwent laparoscopic surgery for ASBO and were admitted to our unit between December 2014 and October 2022 were retrospectively evaluated. The patients were categorized into two groups: patients who underwent complete laparoscopy approach (Group 1) and patients converted to open technique (Group 2). Demographic, clinical, and radiological features, intraoperative findings, and postoperative outcomes were compared. A total of 168 patients were enrolled: 100 patients (59.5%) were included in Group 1, and 68 patients (40.5%) were included in Group 2. The rate of ischemia (p = 0.023), surgical complications (p = 0.001), operative time (p < 0.0001), days of nasogastric tube maintenance (p < 0.0001), time to canalization (p < 0.0001), and length of hospital stay (p < 0.0001) were significantly higher in Group 2 than Group 1. Following univariate analysis, the presence of feces signs (p = 0.044) and high mean radiodensity of intraperitoneal free fluid (p = 0.031) were significantly associated with Group 2 compared with Group 1. Following multivariate analysis, the feces sign was a significant predictive factor of conversion (OR 1.965 [IC 95%]; p = 0.046). Laparoscopic treatment is a safe and effective approach in patients affected by ASBO. The feces sign may be a predictive factor of conversion and could guide the surgeon in selecting the appropriate management of patients affected by ASBO.

BACKGROUND: Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma. METHODS: This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement. RESULTS: A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma. CONCLUSIONS: The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

BACKGROUND: Laparoscopic postoperatives outcomes in adhesiolysis are promising but conversion and morbidity remains high. The objective of our study was to determine preoperative factors to individualize and select the most appropriate approach for each patient. METHODS: Patients ≥18 years old undergoing emergent surgery for adhesive small bowel obstruction and internal hernias were evaluated. Bivariate and multivariate analysis were performed to investigate factors related to conversion to open surgery and to the type of adhesions. RESULTS: Of 333 patients, 224 were operated by laparotomy and 109 by laparoscopy (conversion rate: 40%). Previous abdominal wall mesh, type of adhesions, bowel lesion, need for intestinal resection and laparoscopic skills were statistically related to conversion. In the multivariate analysis, complex adhesions (OR 4.3, 95% CI 1.5-12.2; P = 0.006), the need for intestinal resection (OR 14.16, 95% CI 2.55-78.68; P = 0.002), and non-advanced laparoscopy surgeons (OR 4.31, 95% CI 1.56-11.94; P = 0.005) were independent factors for conversion to open surgery. ASA III-IV, previous surgeries, previous abdominal mesh and previous adhesiolysis were related to complex adhesions. Previous laparoscopic surgery and internal hernia or closed loop in computed tomography were associated with simple adhesions as a cause of the obstruction. In the multivariate, previous adhesiolysis (OR 4.76, 95% CI 1.23-18.3; P = 0.023) and the findings on computed tomography were significantly related with the type of adhesion. CONCLUSION: Some preoperative factors allow to individualize the surgical approach in the adhesive small bowel obstruction improving surgical outcomes.

BACKGROUND: Small bowel obstruction (SBO) is responsible for 350,000 U.S. hospitalizations and costs ~ $2.3 billion annually. The current standard of care for SBO is to trial 3 to 5 days of non-operative management. This study evaluated the factors associated with operative management. METHODS: This retrospective cohort study included adult patients admitted with adhesive SBO. Exclusions were for operative intervention within 24 h or death. RESULTS: At baseline (N = 360), mean age was 65.9 years, 57.8% female, 72.3% white, mean BMI 26.1, 38.7% with history of SBO and 98.1% had history of abdominal surgery. Symptom onset prior to hospitalization was 1-2 days. 55.6% had successful non-operative management at discharge (median length of stay 3 days) vs. 44.4% operative conversion. In univariate analyses, BMI, SBO history, surgical history, days symptom onset, vitals, abdominal pain, obstipation, acute kidney injury, and lack of small bowel feces sign on CT scan were significantly associated with operative management. In a multivariable logistic regression, after controlling all other variables, a lack of small bowel feces sign (adjusted odds ratio, aOR = 2.25, 95% CI 1.06-4.77, p = 0.04) and history of exploratory laparotomy (aOR = 0.44, 95% CI 0.21-0.90, p = 0.03) were significantly associated with operative management. Time from admission to surgery averaged 3.89 days: small bowel resection (55/160) was 4.9 days (median = 4), compared to patients without resection (3.4 days, median = 2; p = 0.00; OR = 1.2, 95% CI 1.07-1.35). CONCLUSIONS: A lack of small bowel feces sign can be a potential indicator for operative management and should be further explored. Since the median resolution of symptoms in the non-operative management group was ~ 2 days and a 20% higher odds for bowel resection each day surgery is delayed, the conservative trial period for adhesive SBO should not exceed 3 days.

Background: The accurate diagnosis of adhesive small bowel obstruction (ASBO) is challenging for surgeons. The aim of this study was to demonstrate that pneumoperitoneum 3-dimensional volume rendering (3DVR) can provide an accurate diagnosis and has applicability in ASBO. Methods: In this retrospective study, patients who underwent preoperative pneumoperitoneum 3DVR and surgery for ASBO between October 2021 and May 2022 were enrolled. The surgical findings were taken as the gold standard, and the kappa test was used to verify the consistency of the pneumoperitoneum 3DVR results and surgical findings. Results: A total of 22 patients with ASBO were included in this study, 27 sites of obstruction adhesions were found during surgery, and 5 patients had both parietal adhesions and interintestinal adhesions. Sixteen parietal adhesions (16/16) were found using pneumoperitoneum 3DVR (κ=1.00; P<0.001), and the diagnosis of parietal adhesions on pneumoperitoneum 3DVR was perfectly consistent with the surgical findings. Eight (8/11) interintestinal adhesions were found using pneumoperitoneum 3DVR (κ=0.727; P<0.001), and the diagnosis of interintestinal adhesions on pneumoperitoneum 3DVR was substantially consistent with the surgical findings. Conclusions: The novel pneumoperitoneum 3DVR is accurate and applicable in ASBO. It can help personalize the treatment of patients and can be useful in planning a more effective surgical approach.
RESUMO
BACKGROUND: Decompression of the intestine with a long tube or nasogastric tube is the first-choice treatment for adhesive small bowel obstruction (ASBO). Scheduling surgery while weighing the risks of surgery against conservative care is a crucial factor in clinical decision-making. Whenever feasible, unnecessary surgeries should be avoided, and it is essential to provide clinical markers for this. This study aimed to obtain evidence regarding the optimal timing of ASBO and when conservative treatment options are not successful. METHODS: The data of patients diagnosed with ASBO and receiving long tube insertion for more than 7 days were reviewed. We investigated transit ileal drainage volume and recurrence. The primary outcomes were the change in the drainage volume from the long tube over time and the percentage of patients who required surgery. We evaluated some cutoff values to determine the indication for surgery based on the insertion duration and volume of long tube drainage. RESULTS: Ninety-nine patients were enrolled in this study. Fifty-one patients showed improvement with conservative treatment, whereas 48 ultimately required surgery. When a daily drainage volume of ≥500 mL was considered an indication for surgery, 13-37 cases (25%-72%) would be judged unnecessary within 6 days of long tube insertion, while 5 cases (9.8%) would be judged unnecessary on day 7. DISCUSSION: Unnecessary surgical interventions for ASBO might be avoided by assessing the drainage volume on day 7 after inserting a long tube.

BACKGROUND: Preoperative diagnosis of the cause of adhesive small bowel obstruction (ASBO) is very challenging for surgeons. We aimed to develop a nomogram model for the identification of banded adhesions (BA) and matted adhesions (MA) of ASBO. METHODS: This retrospective study enrolled patients with ASBO between January 2012 and December 2020, classified into BA and MA groups according to the intraoperative findings. A nomogram model was developed by using multivariable logistic regression analysis. RESULTS: A total of 199 patients were included, with 117 (58.8%) cases of BA and 82 (41.2%) cases of MA. There were 150 patients designed for training the model, and the other 49 cases for validation. Multivariate logistic regression analysis showed that prior surgery for once (p = 0.008), white blood cells (WBC) (p = 0.001), beak sign (p < 0.001), fat notch sign (p = 0.013), and mesenteric haziness (p = 0.005) were independently associated with BA. The AREA under the receiver operating characteristic curve (AUC-ROC) of the nomogram model in the training and validation sets were 0.861 (95% CI 0.802-0.921) and 0.884 (95% CI 0.789-0.980), respectively. The calibration plot demonstrated a good agreement. A decision curve analysis demonstrated that the nomogram model was clinically useful. CONCLUSIONS: The multi-analysis of the nomogram model might have a favorable clinical applicability for the identification of BA and MA in patients with adhesive small bowel obstruction.
